Areciprocating single-acting pump has a cylinder of 125mm bore and 300mm stroke and draws water from a sump whose water level is 1m below the axis of the pump. the suction pipe is 2 m long and has a diameter of 50mm. calculate the speed in rpm at which separation occurs, if this takes place when the absolute pressure in the cylinder falls to 2.4m of water. atmospheric pressure is equivalent to 10.3m of water. assume simple harmonic motion of the piston. what is the maximum theoretical discharge in litres/min of this pump?

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
